Train Sim World 6: West Coast Main Line: Crewe - Preston

Of course another beautiful addon from just trains. Quite rough stuttering, definitely needs some more optimization even for TSW standards. There is also quite a bit behind other dlc. If you want the full experience I'd recommend Carlisle, Blackpool and Trans-Pennine. You can also get Tees Valley for some extra freight timetables as this addon uses a HEA hopper from Tees.
